Abstract (en)
[origin: WO2019063679A1] The invention relates to an inductive proximity switch. The object of the invention to present a very simplified inductive position sensor, which can be reliably used for detecting a zero crossing of its output voltage when a target moves by will be solved by an inductive proximity switch comprising a transmitter coil, a receiver coil, an integrated circuit for excitation of the transmitter coil and a signal processing unit for processing a received signal from the receiver coil, wherein an oscillator excites a resonant circuit comprising the transmitter coil and a parallel capacitor for inducing a voltage in the receiver coil, wherein the receiver coil comprises two symmetrical segments with opposite orientation that are connected in series, wherein the transmitter coil surrounds the segments of the receiver coil or the transmitter coil is surrounded by the segments of the receiver coil.
